Utility model content

The purpose of this utility model is to provide a kind of slotting spring binding post, by being provided with contact piece in insert part and compressing the tabletting of contact pin under line ball portion is arranged, reaches the effect compressed by inserted sheet.

Above-mentioned technical purpose of the present utility model has the technical scheme that a kind of slotting spring binding post, including in integrated line ball portion and insert part, described insert part deviates from one end, line ball portion and is formed with slotting chamber, be extended with contact piece towards insert part at the slotting chamber of described insert part, described insert part near line ball portion integrally formed with for compressing the tabletting of contact piece.

By using technique scheme, inserted sheet inserts cavity and is connected in insert part, insert the contact piece above chamber conflict at wafer surface and compressed by inserted sheet by tabletting simultaneously, tabletting is carried out the spacing of vertical direction, therefore tabletting is fixed on slotting intracavity and is not easy to loosen, and desirably prevents tabletting and gets loose with insert part.

This utility model is further arranged to: described contact piece is movable spring slice.

By using technique scheme, contact piece is interference fit with space and the inserted sheet of the bottom formation of insert part, and movable spring slice has elastic performance, the movable spring slice deformation when tabletting inserts, it is simple to compress after the insertion of tabletting.

This utility model is further arranged to: described movable spring slice is Z-shaped, and it includes integrated long portion and two short portions, and two described short portions are positioned at the two ends in long portion.

By using technique scheme, long portion and junction, two short portions are formed with abutment, and one of them is used for abutting compression inserted sheet, and another is conflicted to and inserts intracavity, improves the service life of movable insert.

This utility model is further arranged to: described short portion and long portion angle angle are in the range of 150 °-160 °.

By using technique scheme, advantageously forming smooth curved surface so that while compressing inserted sheet, another abutment to the pressure inserting cavity wall will not be excessive, thus realizes improving the service life of movable spring slice.

This utility model is further arranged to: described tabletting is positive stop spring plate.

By using technique scheme, it is achieved to compressing movable spring slice, increase the movable spring slice thrust to tabletting.

This utility model is further arranged to: described positive stop spring plate deviates from insert part one end and arranges in pushing against long portion.

By using technique scheme, long portion is close in insert part near side, line ball portion, and shorter positive stop spring plate can be conflicted long portion, therefore can use shorter positive stop spring plate equally, reach to compress the effect of contact piece.

This utility model is further arranged to: described line ball portion includes that described riveting line skin foot is positioned at described riveting core instep from insert part side all in upwardly extending riveting core foot and the riveting line skin foot of setting.

By using technique scheme, riveting core foot is used for compressing copper cash, and riveting line skin foot is wrapped in the rubber in outside for compressing.

Detailed description of the invention

Below in conjunction with accompanying drawing, this utility model is described in further detail.

As it is shown in figure 1, the structural representation of a kind of slotting spring binding post, including two parts, line ball portion 1 that two parts are formed in one and insert part 2.

Wherein line ball portion 1 includes the most upwardly extending riveting line skin foot 8 and riveting core foot 7, riveting line skin foot 8 and riveting core foot 7 are all symmetrically arranged with two, the copper cash being wrapped in copper wire is placed in line ball portion 1, use the clamp systems such as pliers by two riveting line skin feet 8 to intrinsic pressure so that two riveting line skin feet 8 compress the rubber being positioned at outside copper wire；The most again by two riveting core feet 7 to intrinsic pressure, copper wire is compressed by two riveting core feet 7.

Furthermore, the riveting line skin foot 8 of the same side and riveting core foot 7 are set in distance, rubber and copper wire are separately compressed by staff, because by controlling to apply different pressures size for rubber and copper wire, rubber and copper wire can more preferably be compressed by riveting line skin foot 8 and riveting core foot 7, and copper cash is not easy to get loose after being fixed at line ball portion 1.

Shown in Fig. 2 Fig. 3, the insert part 2 that the present embodiment includes is for grafting inserted sheet, makes isolate two wires be conducted and can conduct electricity by insert part 2 and inserted sheet.Insert part 2 only fastens with inserted sheet, easily loosens during life-time service, and therefore the present embodiment offers the slotting chamber 3 for grafting inserted sheet in insert part 2, offers the groove for fastening inserted sheet in the bottom of insert part 2, does not shows in figure.nullIn order to prevent inserted sheet from getting loose，Simultaneously at this in slotting chamber 3 away from one end, line ball portion 1 to insert embedding in integrally formed with the contact piece owing to pushing against inserted sheet，Use Z-shaped and there is the movable spring slice 4 of elastic performance as contact piece，Movable spring slice 4 includes the long portion 41 being positioned at centre and is connected to the short portion 42 of both sides, long portion 41，Junction is abutment，And long portion 41 is 150 °-160 ° with the angulation scope in short portion 42，Preferably，Use 156 °，Movable spring slice 4 is made to have smooth curve，On the one hand resistance when inserted sheet inserts is reduced，On the other hand the abutment being positioned at slotting chamber 3 is made to conflict the conflict area of insert part 2，Improve the service life of movable spring slice 4，Furthermore the area of conflict inserted sheet at another conflicts point 6，Increase and inserted sheet is pushed against power，Reach the purpose that inserted sheet is not easy to get loose from insert part 2.

Extend to contact piece at line ball portion 1 in insert part 2 simultaneously and be formed with tabletting, use and there is the positive stop spring plate 5 of elastic performance as tabletting, positive stop spring plate 5 is in downward-sloping setting, the upper surface in its long portion 41 of conflicting away from insert part 2 one end, positive stop spring plate 5 had position-limiting action, increase the clamping force of the clamping inserted sheet of movable spring slice 4, prevent from causing movable spring slice 4 to bend because inserted sheet is blocked up, and the movable spring slice 4 simply using elasticity can deform upon with inserted sheet interference fit because of long-term, and positive stop spring plate 5 is set and acts on downwards after movable spring slice 4 makes its deformation and can reset.

This specific embodiment is only to explanation of the present utility model; it is not to restriction of the present utility model; the present embodiment can be made after reading this specification by those skilled in the art as required does not has the amendment of creative contribution, but as long as all being protected by Patent Law in right of the present utility model.
